A corneal ulcer is an open sore or infection on the cornea, the clear front surface of the eye.
It usually occurs due to infection, injury, or severe dryness, and can rapidly worsen if not treated on time.
Corneal ulcer is an eye emergency.
Delayed treatment can lead to permanent vision loss or blindness.
The cornea:
Allows light to enter the eye
Plays a major role in focusing vision
Protects the eye from dust, germs, and injury
Any damage or infection of the cornea can cause severe pain and sudden vision problems.
Corneal ulcers are most commonly caused by:
Bacterial infection (common in contact lens users)
Fungal infection (after injury with soil/vegetation)
Viral infection (Herpes Simplex)
Parasitic infection (Acanthamoeba)
Eye injury or foreign body
Improper contact lens use
Severe dry eye
Vitamin A deficiency
Long-term steroid eye drop use
Weak immunity or diabetes
Symptoms usually appear suddenly and worsen quickly:
Severe eye pain
Redness of the eye
Blurred or reduced vision
White or grey spot on the cornea
Excessive watering or discharge
Sensitivity to light
Swelling of eyelids
🚨 Do not ignore eye pain or redness—early treatment saves vision.
You are at higher risk if you:
Use contact lenses (especially overnight use)
Have diabetes
Have dry eyes
Have eye injury
Use steroid eye drops without prescription
Have weak immunity
Diagnosis is done through:
Slit-lamp eye examination
Corneal staining tests
Corneal scraping for lab testing (if needed)
Early diagnosis helps identify the exact cause and start targeted treatment.
Treatment depends on the cause of the ulcer:
Antibiotic eye drops – for bacterial ulcers
Antifungal eye drops – for fungal ulcers
Antiviral medicines – for viral ulcers
Pain relief & supportive drops
Strict avoidance of contact lenses
⏱️ Eye drops may be needed frequently, even hourly in early stages.
If the ulcer is deep, spreading, or not responding to medicines:
Hospital admission may be required
Intensive monitoring is done
Advanced medical care is provided
In advanced cases:
Therapeutic corneal surgery
Corneal transplant (to save vision or the eye)
Procedures to prevent corneal perforation
Early treatment significantly reduces the need for surgery.
Vision improves gradually with healing
Regular follow-ups are essential
Scarring may occur in deep ulcers
Early care gives the best visual outcome
Never stop medications without medical advice.
Maintain proper contact lens hygiene
Never self-medicate eye drops
Wear eye protection during outdoor work
Treat dry eyes properly
Control diabetes
Seek immediate care for eye injury or redness
🚨 Seek urgent eye care if you have:
Severe eye pain
Red eye with vision loss
White spot on the eye
Injury to the eye
Sudden light sensitivity
Early treatment can save vision.
A corneal ulcer is an open sore on the cornea, the clear outer layer of the eye. It is often caused by infections, trauma, or underlying eye conditions. If left untreated, it can lead to serious complications, including vision loss.
Corneal ulcers are usually caused by bacterial, viral, fungal, or parasitic infections. They can also result from eye injuries, contact lens misuse, severe dry eye, or chemical burns.
Common symptoms include eye pain, redness, blurred vision, sensitivity to light, excessive tearing, and a feeling of something in the eye. If the ulcer is advanced, pus-like discharge may occur.
Treatment depends on the cause of the ulcer. Antibiotic, antifungal, or antiviral eye drops are commonly prescribed. In severe cases, surgery, such as a corneal transplant, may be necessary to restore vision.
No, corneal ulcers typically do not heal without medical treatment. Prompt care is essential to prevent complications and preserve vision.
